Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A fabric softener composition comprising an aqueous dispersion containing between about 0.1 and 10 wt. % of a di(secondary alkyl) ammonium ester derivative corresponding to the formula: ##EQU1## wherein R 1 and R 2 are the same and are C 10 -C 30 secondary alkyl groups: R 3 is selected from the group consisting of hydrogen, methyl, (CH 2 CH 2 O) n H group with n = 3; R 4 and R 5 are selected from the group consisting of alkyl, aryl and aralkyl radicals of from 1 to 10 carbons, and X is an anion selected from the group consisting of sulfate and phosphate z is an integer equal to the valence of X.
Claim 2
Dependent Claim
